Fenofibrate reduces lipoprotein associated phospholipase A2 mass and oxidative lipids in hypertriglyceridemic subjects with the metabolic syndrome

Rosenson, Robert S.·2008·American Heart Journal

Abstract

Background Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a macrophage-synthesized lipase that is primarily bound to small electronegative low-density lipoproteins (LDLs). Lipoprotein-associated phospholipase A2 oxidatively modifies LDL and generates the proinflammatory byproducts oxidized fatty acids (ox-FAs) and lysophosphatidylcholine. Fenofibrate reduces Lp-PLA2 mass; however, it remains unknown whether the anti-inflammatory effects of fenofibrate are related to changes in LDL subclasses. Methods This was a randomized, double-blind, controlled clinical trial designed to investigate the effects of 3-month treatment with fenofibrate (160 mg/d) on Lp-PLA2 mass, LDL subclasses, and ox-FAs among 55 hypertriglyceridemic (> or = 1.7 and < 6.78 mmol/L) subjects with the metabolic syndrome. Results Fenofibrate treatment lowered fasting Lp-PLA2 mass by 13.2% (-19.0 to -7.7) versus placebo (2.3% [-5.0 to 4.1], P = .0002) and total ox-FA by 15.5% (-34.2 to +1.4) versus an 11.5% increase with placebo (P = .0013). In age-, sex-, and treatment-adjusted models, changes in Lp-PLA2 mass were associated with reductions in chemical LDL cholesterol (r = 0.59, P < .01) and measured total LDL particles (LDL-Ps) (r = 0.64, P < .01) and small LDL-Ps (r = 0.57, P < .01). In models that included small LDL, effects of fenofibrate on Lp-PLA2 mass were attenuated (P = .125), but not in models that included LDL cholesterol (P < .0001) and LDL-Ps (P = .005). Changes in Lp-PLA2 mass were not significantly associated with changes in ox-FA or inflammatory markers. Conclusions Among hypertriglyceridemic subjects with the metabolic syndrome, fenofibrate therapy reduced Lp-PLA2 mass, and these changes were associated with fewer small LDL-Ps.

  • Fenofibrate treatment typically reduces serum triglycerides by a mean change of −93.7 mg/dL (−39.3%), increases high density lipoprotein cholesterol by +5.5 mg/dL (+12.4%), and reduces low density lipoprotein cholesterol by −17.9 mg/dL (−12.3%).

    “Typical changes in serum lipids as a result of FF treatment include clinically important mean reductions of serum triglycerides (TG) by a mean change of −93.7 mg/dL (−39.3%), increases of high density lipoprotein cholesterol (HDLC) by +5.5 mg/dL (+12.4%), and reductions in low density lipoprotein cholesterol (LDLC) by −17.9 mg/dL (−12.3%).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
